What viral infection that leads to the integration of the viral genome into the host cell genome?
Lysogenic cycle
What is true about a lysogenic infection?
Many viruses enter the lytic cycle immediately following infecting the host cell. However, some viruses may not lyse their host immediately and enter the lysogenic cycle. At the start of the lysogenic cycle, the virus genome is integrated into the host chromosome instead of being immediately transcribed and translated. The virus genome then lies dormant in the host chromosome until a later event triggers its excision from the host chromosome. The excised viral genome will then be transcribed and translated and the virus enters the lytic cycle. the virus hides in the host's DNA.
What technique has been applied to studying the timing of replication initiation in different regions of the genome?
The time of replication initiation can be measured through MICROARRAY ANALYSIS because it uses flourecent labelled nucleotide.
What is the lyctic cycle?
I suppose you mean "lytic cycle". It's the reproductive cycle of virus in which upon entering the host, the viral genome directs the host genome to produce viral proteins and after assembly and maturation of viral particles, they get released by host lysis. There is another cycle called lysogenic cycle in which the viral genome integrates with the host instead of causing lysis.
How do eukaryotes speed the process of replication-since they have multiple long chromosomes?
The eukaryotic genome is so much larger than the prokaryotic genome that it would not be practical to rely on a single origin of replication site when copying it for cell division. By incorporating several, the eukaryotic cell can divide without unnecessarily long delay in chromosomal replication.

What has the author Melvin L DePamphilis written?
Melvin L. DePamphilis has written: 'Genome duplication' -- subject(s): DNA replication, Genome, Gene Duplication 'Concepts in eukaryotic DNA replication' -- subject(s): DNA replication
What is the mode of action of nucleoside and nucleotide analogs?
Nucleoside and nucleotide analogs inhibit viral replication by incorporating into the viral genome during replication. These analogs lack the necessary functional groups for further elongation of the viral genome, leading to termination of viral replication and inhibition of viral protein synthesis. This disruption ultimately stops the virus from spreading and replicating.
What is the difference between a virus and lentivirus?
Well, a virus refers both lysogenic and lytic varieties. A lentivirus is a family of viruses that follow the lysogenic model of infection where the genetic information of the virus is integrated into the host cell's genome. What makes the lentivirus useful as a vector in genetic research is that it is the only type of virus capable of penetrating the nucleus, that is, it can infect the host's genome at any point in the cell cycle where every other lysogenic virus can only infect during phases of the cell cycle that see the nucleus broken down.
Difference between eukaryotic DNA replication and bacterial replication?
The difference between Eukaryotic DNA and bacterial genome replication is the eukaryotic DNA is mostly linear and has multiple sites of replication. They both are bidirectional.
Where does replication of a genome take place?
genomic replication, or DNA replication, is performed by multiple enzymes that together are called a replicase. This replication takes place within the nucleus of a cell
What happends durning DNA replication?
The entire genome is replicated, preparing the cell for mitosis.
What does it mean for a virus to have a lysogenic reproductive cycle?
The lysogenic cycle replicates the phage genome without destroying the host. Similar to Lytic reproduction, Lysogenic also begins when the phage inserts its DNA or RNA into the host cell through its surface. Once the nucleic acid is inside the cell, it forms a circle, and becomes a part of the genome of the host cell. It does this through genetic recombination, or crossing over. Once it joins the host’s genome, it is called a prophage. Since it is a part of the host cell’s genome, the phage’s genetic information is copied and distributed to the daughter cells of the host cell, which continues dividing naturally. This allows the prophage to be repeatedly copied and passed on without destroying the host cell it depends on for metabolic and reproduction purposes. In order for actual active phages to be produced, the segment of genome from the original phage exits the genome of the host cell and becomes independent. When this occurs, it begins the lytic cycle, destroying the cell, but producing new and functional phages.
What strategies would allow you to determine if a bacterial colony had been infected with a lysogenic virus?
Gel electrophoresis to assess the size of the bacterial genome.
Why is accurate replication of genes important for mitosis?
In order to produce identical genome in daughter nuclei
